I am not talking about how to check JS.
I am asking about an efficient workflow to deal with JS-snippets (doing ajax-stuff with jquery) that are embedded in a Perl-module.
So mentioning mozrepl or Mech::FF is if no value to me (I know about these) unless there is a concrete way to incorporate them into a workflow.
Of course I could try to hack something together to extract the JS from my module, send it to a browser via mozrepl and so on but I am more hoping for tools I could just use (rather then develop myself).
A long shot, I know...
